Favors well against Mino G 28-70/2.8 scoring 3.7 and Mino 28-135/4 scoring 3.6. The Tammy is like a nice combination of the two Mino's put into one lens.

Reading the actual MTF ratings, you'll notice the Tammy is better at telephoto than either Minolta. Notice the huge jump in IQ at telephoto by f/4, beyond the Mino's. Lens can serve you well if you get to know it.
